Company who claims 4G in mountains cannot even provide 3G in plains




I have been using Airtel for past 2 years in different forms and was quite excited that they had launched 4G services. But my happiness was short lived. The dongle which was supposed to provide 4G services could not even provide good 3G services. In most of the cities I visit in India either it is 2G or barely 3G. It is even more appalling is the way they claim about the 4G services in the Ads. It almost feels like I am being taken for a ride. I hope and pray that some day a service will come which will put customer and real customer experience in the forefront and actually provide what they claim.

Over 2 million co-infected with HIV, hepatitis C

Of these, more than half, or 1.3 million, are people who inject drugs (PWID) -- HIV infections caused by injecting drugs.

The study revealed that HIV-infected people are on an average six times more likely than HIV-uninfected people to have HCV infection.

The study shows that not only are people with HIV at much higher risk of HCV infection, groups such as people who inject drugs have extremely high prevalence of HCV infection - over 80 percent.

HIV and HCV infections are major global public health problems, with overlapping modes of transmission and affected populations.

Globally, there are 37 million people infected with HIV and around 115 million people with chronic HCV infection.

Improvement in the surveillance of HCV and HIV is imperative to help define the epidemiology of coinfection and inform appropriate policies for testing, prevention, care and treatment to those in need.

The study shows the need to scale up prevention interventions, such as needle and syringe programmes and opioid substitution therapy, as well as access to HIV and HCV treatment, to reduce morbidity and new infections, the researchers suggested.

The study, published online in The Lancet Infectious Diseases, systematically reviewed 783 medical studies from worldwide sources to build the first global estimates on the prevalence of HIV/HCV co-infection (measured by HCV antibody) as a public health problem.

Breath test analyzer could help detect liver disease at early stage

In the journal EBioMedicine, a study led by the University of Birmingham in the UK suggests that high levels of a natural compound called limonene in the breath could be a sign of early-stage cirrhosis of the liver.

Researchers say that we already know that the breath of people with liver disease has a very distinct smell, and they wanted to find out what causes it. Now they have found a biomarker for the disease in limonene, they can continue to verify how good it is for diagnosing liver disease.

Limonene is a natural compound found in fruits and vegetables and in abundance in citrus fruits like oranges and lemons. It is also found in cosmetics, perfume and cleaning products and is used to flavor candies.

Because symptoms tend to be vague and often mild during the early stages, patients with liver disease do not usually seek medical advice until the condition is advanced and the liver is more damaged. Even then, symptoms can be mistaken for other diseases. They can include fatigue, jaundice, bleeding, swelling, bruising easily, confusion and nausea.

Cirrhosis is where continuous, long-term damage causes the liver to become so scarred it cannot function properly. The disease can lead to liver failure and cancer.

In the UK, where the new study took place, liver disease has risen sharply in recent decades to become the third biggest cause of early death, with 75% of deaths being alcohol related.

Breath levels of limonene higher in patients with liver cirrhosis

Researchers carried out their study in two phases. First, they compared breath samples from 31 patients with liver cirrhosis with those from 30 healthy controls.

In the second phase, they compared breath samples taken before and after liver transplants. The before samples came from the same 31 patients as in the first phase, and the after samples came from 11 of those patients who went on to have liver transplants.

The breath samples were analyzed with a mass spectrometer. For phase 1, this showed that the level of limonene in the patients with liver cirrhosis were much higher than in the healthy controls.

The researchers say this is probably because a diseased liver cannot fully metabolize limonene.

The phase 2 analysis showed that the levels of limonene gradually dropped in the transplant patients in the days following receipt of their new organ.

Limonene is 'unambiguously associated with diseased liver'

There have been previous attempts to find possible biomarkers for liver disease but these have suggested compounds like isoprene and acetone, which are not specific enough since they can also be indicative of other diseases or even arise naturally from normal metabolic activity.

Researchers wanted to find a biomarker that is unambiguously associated with diseased liver. If the further research is successful, in the future we can envisage a small portable breath analyser that can be used by GPs and other health professionals to screen for early-stage liver disease, leading to earlier treatment and better survival rates.

A particularly important advantage of breath tests is that they offer the opportunity to assess the global function of the liver, rather than a localized test such as biopsy.

The study is important, because for the first time it opens a potential route to noninvasive, real-time detection of early-stage liver disease. The researchers conclude that If that is possible, then the disease could be reversed by drugs and lifestyle change which would lead to major socioeconomic impacts.

Khatore Pharmaceuticals and other organisations work to spread awareness about hepatitis

With over 3/4 of people in India being unaware about the existence of Hepatitis, many medical exerts of the country have decided to start an online data registry detailing the rising number of hepatitis patients. Khatore Pharmaceuticals also ran a campaign in Delhi to make people aware of liver disorders including distributing pamphlets to people near metro stations.

Hepatitis is an inflammation of the liver. The aim is to make people aware of problem and precaution that they can take to prevent it from spreading. 

The registry will be part of the newly formed Indian National Association for Study of Liver and Current Perspective in Liver Disease constituted by the leading gastroenterologists of the country. The association will also disseminate information to the regional hospitals and help the health centres located in remote areas of the country get the medicine supply.

Talking about lack of awareness about the deadly disease, the experts said that Hepatitis was 28 times more dangerous than AIDS due to the absence of symptoms, even as the disease spreads gradually in the patient.

Four lakh people die due to liver diseases, a result of hepatitis, in India every year. The states most affected by the disease are Punjab, Haryana, Odisha, Uttrakhand and Himachal Pradesh among few others, they said.

75% of the hepatitis, may it be B or C, is curable at the initial stage. However, as the symptoms are not felt, the person gets to know about it only when the virus causes liver cancer.

Through the registry, the hot spots of Hepatitis across the country can be brought into lime light and accordingly medical healthcare in those areas can be improved, precisely the treatment for liver diseases.

Resistance training can help patients suffering from fatty liver disease

Resistance training also called strength training or weight training in the gym leads to a fall in liver fat levels. This is the finding of a new study held at the University in Tel Aviv. According to experts, for patients suffering from physical limitations or low motivation that prevents them performing aerobic exercises, resistance training can be an effective alternative.

On the basis of past studies, fatty liver disease is defined as a fat rate in excess of 5-10 percent of liver volume. The disease affects approximately 30 percent of the public and is considered the commonest liver disease in the Western world. Excessive weight, abdominal obesity, diabetes, dyslipidemia, and in particular triglycerides increase the risk of developing fatty liver disease, which can lead to inflammation and cirrhosis of the liver.

The disease is usually asymptomatic, although patients sometimes report fatigue and a lack of vitality by comparison to healthy individuals. Fatty liver causes morbidity and mortality due to metabolic complications such as diabetes and cardiovascular disease, the development of cirrhosis and liver cancer. Although patients with the disease recognize the importance of physical activity, they often lack the motivation to engage in such activity, particularly in the case of aerobic exercises, which are usually time consuming.

The researchers decided to examine the impact of resistance training - which is usually briefer and more focused than aerobic exercises - on fatty liver disease. The study included 82 subjects aged 20-65 who were diagnosed by means of an ultrasound as suffering from fatty liver disease over the six months before the beginning of the study. The participants were divided randomly into a resistance training group and a control group that was asked only to undertake stretching exercises. The participants were asked not to change their physical activity habits during the study, to continue their usual diet, and to take their prescribed medicines. During the study the participants underwent examinations of weight, blood pressure, a blood test for liver enzymes, lipids, blood sugar, and insulin. Resistance training in the gym was defined according to a uniform protocol, with the level of resistance adjusted to the patient's capabilities. The training, that was designed and delivered, included several sets of different resistance exercises involving the arms, chest, and legs and lasting for a total of 40 minutes, three times a week.
At the end of the three-month study, the researchers found that resistance training in the gym led to a decrease in liver fat based on the fat content of the liver as detected in the special ultrasound examination employed by the study. The resistance training was not intended to reduce body weight significantly, and indeed overall weight loss was very slight. However, it seems that the resistance training had a specific impact in terms of a fall in liver fat levels as measured in the ultrasound examination.

The study also found that gym training led to a significant fall in blood cholesterol levels. We assume that the physical exercise improves the resistance to insulin, thereby reducing the production of cholesterol in the liver and its level in the blood. This study also shows for the first time that resistance training led to a reduction in ferritin levels in the blood. Ferritin is a protein found in the liver that facilitates the storage of iron. However, elevated levels of ferritin can be indicative of liver damage, including inflammation. Accordingly, a fall in ferritin levels may reflect an improvement in the condition of the liver.

World Hepatitis Day: Mass awareness, immunisation needed to help curb spread of hepatitis

Mass awareness, universal guideline for immunization and hygienic handling of food and water will help curb hepatitis, said experts on Tuesday while observing world Hepatitis Day. About, two million people contract hepatitis every year from unsafe injections. These infections can be averted through the use of sterile syringes that are specifically designed to prevent reuse. Eliminating unnecessary injections is also an effective strategy.

 Experts stressed on the urgent need to enhance action to prevent viral hepatitis infection and to ensure that people who have been infected are diagnosed and offered treatment. The WHO this year, is focusing particularly on hepatitis B and C, which together cause approximately 80% of all liver cancer deaths and kill close to 1.4 million people every year. In addition to hepatitis B and C, hepatitis A and E viruses also cause viral hepatitis. These two viruses are primarily transmitted through contact with contaminated food and water and are responsible for less than 1% of all hepatitis-related deaths.

While explaining about poor target achieved in case of administration of Hepatitis-B0, the experts say "About 30-33% deliveries take place at sub-centres which do not have round-the-clock vaccination facility. Moreover, deliveries at private hospitals most of the time go unrecorded; hence the first dose of vaccination to the newborn within 24 hours remains unattended."

Viral hepatitis is caused by five distinct hepatitis viruses. Infection from these viruses results in approximately 1.45 million deaths each year. These viruses are transmitted through contaminated water and food, as well as by contact with blood or bodily fluids, through unsafe injections or transfusions. Infection also occurs from mother to child, or through sexual contact. Infection through all these routes of transmission can be prevented through proven and effective interventions. It is important for everyone to be aware of hepatitis and to learn how they can protect themselves from being infected.

Focusing on this year's theme - 'Prevent hepatitis. Act now', the workshop discussed various preventive measures.

Medicines are now available that can cure or help control in most people with hepatitis C and hepatitis B infection. People who receive these medicines are less likely to die from liver cancer and cirrhosis and also less likely to transmit the virus to others.

Patients should demand safe injection. Approximately, two million people per year contract hepatitis from unsafe injections. These infections can be averted through the use of sterile syringes that are specifically designed to prevent reuse. Eliminating unnecessary injections is also an effective strategy to protect against hepatitis transmission.

The WHO recommends vaccinating all children against hepatitis B infection, from which approximately 7.8 lakh people die each year.

As per Government of India, the vaccination schedule under the Universal Immunisation Programme for Hepatitis B vaccine is of 4 doses; 0 dose within 24 hours of birth and three doses at 6, 10 and 14 weeks of age.

World Hepatitis Day 2015: Prevent hepatitis. Act now

On World Hepatitis Day, 28 July, the World Health Organisation (WHO) is highlighting the urgent need for countries to enhance action to prevent viral hepatitis infection and to ensure that people who have been infected are diagnosed and offered treatment.

This year, the Organization is focusing particularly on hepatitis B and C, which together causes approximately 80% of all liver cancer deaths and kills close to 1.4 million people every year.

The theme for this year’s World Hepatitis Day is “Prevent hepatitis. Act now”.

In India, it is estimated that prevalence of hepatitis C infection is more than 6 times the prevalence of HIV infection. The World Health Organisation has called the HCV a “viral time bomb”, which signifies that the policy makers must pay the required attention towards this health issue.

WHO is alerting people to the risk of contracting hepatitis from infected blood, infected injections, and sharing drug-injection equipment.

Risk factors, symptoms and causes

Hepatitis A: This form of hepatitis is commonly found in children and is usually spread by fecal-oral contact or fecal-infected food and water.

A baby could get hepatitis A by consuming food/water contaminated with HAV-infected stool.

Parents might not even know that their children have caught the disease as hepatitis A can be a mild infection. However, in serious cases of infection, symptoms include fever, vomiting, fatigue, loss of appetite, abdominal discomfort, dark-colored urine, and jaundice.

Hepatitis A usually causes mild illness, but it can also cause prolonged illness for upto six months

Hepatitis B: The hepatitis B virus is spread by contact with blood and other body fluids of an infected person. Infants may contract hepatitis B if they are born to a mother who has the virus.

In adults, it can be transmitted through unprotected sex with an HBV-infected person and sharing of contaminated needles or syringes for injecting drugs.

Symptoms may range from a mild illness to more serious chronic liver disease that can result in liver failure. Common symptoms may include fever, vomiting, loss of appetite, jaundice, etc.

Hepatitis C: It is more common in adults than in children. Hepatitis C is transmitted through direct contact with human blood and other body fluids. A baby can also get hepatitis C from his/her infected mother.

In adults, it can also be acquired through sexual contact with an infected person or through intravenous drug use.

Symptoms are usually mild and children often show no symptoms at all and therefore, parents get to know about their kid's disease at a later stage.

Hepatitis C leads to chronic liver disease in a majority of people infected with the virus. HCV is also considered to be the leading cause for liver transplantation in adults. Chronic hepatitis C virus infection is also linked with cancer.

Tests and diagnosis

All of the above conditions can be diagnosed through blood tests. A healthcare provider may also ask for liver function tests in order to determine the extent of the damage. A liver biopsy may be asked to do to further check for organ damage. Other tests and diagnostic procedures to determine the extent of the disease include CT scans and MRI.

Prevention

Like any other diseases, practising a good hygiene can help prevent the risk of getting as well as spreading hepatitis. Other preventive measures include:

Vaccinations - vaccinations are available for HAV and HBV, unfortunately, there's no vaccine for HCV.

WHO recommends vaccinating all children against hepatitis B infection. The vaccine should be given as soon as possible after birth, preferably within 24 hours. The birth dose should be followed by 2 or 3 doses to complete the vaccine series. A safe and effective vaccine can protect from hepatitis B infection for life.

WHO also recommends vaccinating adults who are at increased risk of acquiring hepatitis B.

Blood transfusion – to reduce the risk of infection, blood transfusion is routinely screened for hepatitis B and C.
